The Mazza

The surname this archive is named for is also the most fragmented thing in it. A hundred and twenty Mazza sit in six groups that no record joins to each other.

Piedimonte Etneo — 13 September 2026

The marriage, and then the birth: two acts close the deepest Sicilian generation

The parish register was the wrong door. It was browsed to the right year and it held nothing, and the reason turned out to be simple enough to be embarrassing: civil registration began in the south in 1866, so a marriage of about 1870 is a civil act, kept by the comune and now on the Antenati portal — and the civil act is the one that names all four parents.

The annual index of the Piedimonte Etneo marriages of 1871 gives, in a clerk's hand, Mazza Rosario / Bonanno Leonarda — numero di registro 14. Here is the act.

Piedimonte Etneo, Matrimoni 1871, atto 14 — Antenati an_ua83392, images 13–14. Act 15 follows at half past four the same afternoon; the registrar was running a set of weddings that day.

Anna Cavallaro, and a generation the tree does not have

Leonarda Bonanno has stood in this archive as a name with a father's first name attached — daughter of Gaetano, taken from a marriage proclamation of 1910. The act of 1871 gives her both parents: Gaetano Bonanno and Anna Cavallaro. They are the Bonanno equal of Mariano Mazza and Maria Catalano, and like them they are entirely absent from the family tree.

And then his birth, to the day

With the parents fixed, the birth was worth hunting. The Piedimonte birth registers run from 1820 on Antenati, and every volume ends with a table of the whole year's births in act order, giving the child, the comune, both parents and the day — six openings for a year. The table for 1845, at entry 64, reads: Mazza Rosario — Piedimonte — Mazza Mariano / Catalano Maria.

Piedimonte Etneo, Nati 1845, atto 64 — Antenati an_ua72387, image 66. Comune di Piedimonte, distretto di Acireale, Provincia di Catania.

Put the three acts side by side and the deepest Sicilian generation is no longer an inference from anything. Mariano Mazza and Maria Catalano are named as Rosario's parents in his birth act of 1845, in his marriage act of 1871, and in his death act of 1924 — three registers, seventy-nine years apart, one couple. The birth act also does what neither of the others could: it dates them, both at thirty-six in June 1845, so both born about 1809.

One honest note. The marriage act enters Rosario as d'anni ventisei — twenty-six — and his birth act makes him twenty-five and eleven months on the day. Declared ages in these registers are routinely a year out; the birth act is the one to believe.

What is now cheap that was not

Fifty volumes of Piedimonte births, 1820 to 1863, are now written down with their arks. Because each year's table lists both parents and not only the child, it is a finding aid for a couple: reading the parents column down a year finds every child Mariano Mazza and Maria Catalano had in it. Rosario's brothers and sisters, and the generation above Mariano, are a sweep away rather than a search.

Sicily, at last — 13 September 2026

Rosario Mazza's death act, and the name line stops being an inference

The Mazza are this archive's namesake and its oldest unfinished business. The Calabrian work ran hot for a fortnight while Piedimonte Etneo sat untouched. One afternoon on FamilySearch put that right.

The 1845 birth is not a surprise — it is a vindication. This archive derived 1845 from the ages the marriage proclamations gave Rosario in 1898, 1902 and 1910, against a family tree that says 1850, and said so. The death act agrees.

And the name line stops being an inference

The archive reached Mariano Mazza and Maria Catalano the hard way: by reading "di Mariano" off marriage proclamations and assembling a generation nobody had claimed. It was careful work and it was still an inference.

Rosario's own death act names both of them outright. The deepest Sicilian generation in this archive is now a documented fact rather than a reconstruction.

And there is a son nobody had. The Acireale diocesan registers name Rosario Mazza and Leonarda Bonanno as the parents of a Marianum Mazza — a son called for his paternal grandfather, exactly as Sicilian custom predicts of a first son. He is not in the family tree.

The registers spell his father four different ways, which is the practical lesson in them:

Rogerius Mazza
son Salvator
Rosarius Mazza
son Horatius — Orazio
Joannes Mazza
with Leonora Bonanno, son Joannem — Giovanni
Gaspare Mazza
son SANTO
the missing son

The last is the one that matters. Santo Mazza is one of the two sons this archive found missing from the family tree — and here he is in a parish record, under a father's name that reads Gaspare. In these registers the given name is unreliable and the wife's name is the stable handle.

The register browsed, and the range pinned

The parish marriage register was then browsed by hand. The act is not found yet — but it is now cornered. Film 007490025 runs to 2,976 images, and reading pages gives the calibration:

image 919
1898 — Salvatore Mazza's marriage
known
image 849
1888 — entries 65–70
read
image 723
late 1869 — entries 74–79, Die 22 Novembris 1869
read

That is about seven images to the year, so 1870 opens around image 724–726 and the marriage — which their eldest child dates to about 1870–72 — should lie in images 724 to 745. Twenty openings, and the next person to sit down with this does not have to start from 1777.

Notes for whoever continues. The ?i= parameter does not move the viewer — it reverts; the ark in the URL is what identifies an image. The "Enter Image number" box does work, but it commits on click or blur rather than on Enter, and the URL lags behind the viewer. And the fast way to scan is not the Latin page at all — it is the AI-extracted image index below the viewer, which tabulates Name, Father's Name and Mother's Name for every entry on the opening.

Why "Rosario" finds nothing in the parish register

The Piedimonte Etneo parish marriage register runs 1777–1911 and is in the full-text corpus — so Rosario and Leonarda's own marriage, about 1870, ought to be reachable. It is not, and the reason is worth recording.

These registers are in Latin. Salvatore's 1898 parish marriage reads Salvator Mazza, son of Rogerius Mazza and Leonarda Bonanno. Rosario is Rogerius. And even searching that form returns nothing, because the OCR of the hand is so poor that the page text is close to unusable — what actually works on these images is the AI-extracted household index, not the transcript.

Written before the act was found, and left standing. This section ended by saying the marriage was "very probably there" in the parish film and would have to be browsed. It was browsed — twenty openings of it — and it was not there. The film's own index holds no marriage for the pair at all. The act was in the civil register instead, and is set out at the top of this page. The reasoning was sound and the conclusion was wrong, which is the ordinary way of it; the record of the wrong turn is left here because the next person may take the same one.

A two-way conflict becomes a three-way one

The same parish record names Maria Nicotra 's mother as Venera Cosentino. The archive already held two readings: Monti Venera from the 1898 civil proclamation, and Venera Cassaneti from the Queensland death index. That is now three surnames for one woman, with only the given name Venera constant across all of them. Cassaneti and Cosentino may be the same word badly read twice. It stays unresolved, and it is worse than it was this morning.

What the name is

Mazza is the Italian for a club, a mace or a mallet, from the Latin mattea. It became a surname in every available way at once: as a nickname for a strong or a violent man, as a trade name for someone who swung a maul, and — most commonly — from the medieval personal name Mazzo, a short form of Giacomazzo, Tommazzo and the like.

It is among the most widespread surnames in Italy and it was coined independently, many times over, from Lombardy to Sicily. There is no founding Mazza family. That is not a disclaimer — it is the operative fact of this page, and it is why the six groups below are kept apart rather than drawn as one tree.

Group 1

The line that reaches the children

110 people 1850–1952 Piedimonte Etneo, Catania, Sicily · Brisbane, Queensland · Catania, Sicily component 1

Five generations and then it stops: Rosario Mazza — of whom one single fact is known, that he fathered Salvatore — then Salvatore Mazza born at Piedimonte Etneo in 1879, Sebastiano Mazza who sailed on the Toscana in 1949, and down to Mia and Rocco Francesco. It is the shallowest of the four quarters by five generations.

The 8 who still share the name and nothing else

The big one is gone: the hundred and ten Piedimonte Etneo Mazza who once sat here unattached are now part of group one, proved the descendants of Salvatore's brothers by five register acts. What is left are fragments — a handful of people entered with no parent, spouse or child, who cannot be placed either way.

Compare the Arena

Thirty-nine Arena in this tree form one single unbroken family, 1821 to 1937, all of Scilla. A hundred and twenty Mazza form six groups. That is not because the Arena were better recorded — it is because Arena arrived in this archive through one household that had been worked on, and Mazza arrived as a surname. The name a family is known by tells you least about it.
